Better error message when run fix on file not included in tsconfig.json

[egorio]

Currently when user is trying to run rehearsal fix file.ts, but file is not a part of app according to tsconfig.json the error message will be:

$ ~/rehearsal fix src/file.ts
info:    @rehearsal/fix 1.1.1
✔ Initialize
✔ Analyzing project dependency graph ...
✖ Could not find source file: '......../src/file.ts'.

which is confusing, because file is there.

We have to show more actionable error, like: Complier can't find a file. Please check path to file included in tsconfig.json (or make sure path to file is a part of paths, etc.)
