Fix install with local modules under multiple paths #217

I found this issue a few days ago, added a test case, git bisected and found 2f0c883 to be the cause of the problem.

Reverting said commit seems to resolve the problem. Verified it by running npm run tap test/tap/install-from-local-multipath.js before and after the revert on latest.

I tried running the entire test suite and seems like there no failing tests caused by the revert.

Note: I have no idea what I am doing and the author made no changes to tests nor left any notes on the reason for the changes in 2f0c883. Someone with more knowledge should have a careful look what the proper solution should be.

Yeah, I think you've found a bug, but I'm going to have to do a bit of work to understand the solution before believing that it won't cause other problems.

Kicked out to 6.10.3 (at least).

@isaacs looks like a package-lock.json created before the "fix" is partially rewritten by an npm install after the fix. Might be an unwanted effect, shall I post some examples?

@salomvary yeah, reproduction examples are always great, thanks :)

@isaacs given an existing package-lock.json and an empty node_modules folder, the patched version does rewrites like this:

     "my-shared-project": {
-      "version": "file:../parent-folder-of-shared-projects/my-shared-project",
-      "requires": {
-        "ajv": "^6.5.0",
-        "ajv-keywords": "^3.2.0",
-        "ajv-merge-patch": "^3.0.0",
-        "clone": "^2.1.2",
-        "dot-prop": "^4.2.0",
-        "json-schema-ref-parser": "^4.1.1"
-      }
+      "version": "file:../parent-folder-of-shared-projects/my-shared-project"
     },

This builds on the work of #217, bringing
back the logic in 2f0c883 for all deps
other than 'directory' symlinks where it causes problems.

This also causes the installer to *fix* shrinkwraps that inappropriately
list the dependencies of directory symlink packages, which goes further
to address the problems highlighted in
https://npm.community/t/installing-the-same-module-under-multiple-relative-paths-fails-on-linux/8863
and
https://npm.community/t/reinstall-breaks-after-npm-update-to-6-10-2/9327,
even if a prior npm install created a broken package-lock.json file.

Ok, got a chance to review this. Turns out, yes, this fix does have some other side effects, and doesn't address the problem for all cases. The rest of the fix is on 45772af.

It will be in the next release.
