Update lodash.create

[bdsomer]

As you can see through this visualization, updating lodash.create would drastically reduce the number of dependencies that mocha has, causing faster install times and occupying less disk space.

Thanks for the PR! This sounds really helpful; I was looking for ways to cut down on install time not too long ago.

To be sure the new version works in all the environments Mocha supports, I think we'll want to rebase this after we get the JWT stuff for SauceLabs set up so that the Travis jobs are actually testing all the browsers (whereas right now there's a separate job for each browser but for PRs from forks they redundantly test PhantomJS instead).

@ScottFreeCode Okay, sounds good!

See #2979; lodash.create may be able to be dropped when that happens.

[boneskull]

linking this to #3018. (implying that this can likely be closed and we can drop lodash.create altogether when I get to #3018)

[boneskull]

ok, we don't need this. thanks anyhow!

[bdsomer]

@boneskull Sounds good!
