Add projectile-cache-file to projectile-globally-ignored-files default

[takeokunn]

Summary

Fix #1958 - Exclude .projectile-cache.eld from search results by default.

Changes

• Add projectile-cache-file to the default value of projectile-globally-ignored-files
• This prevents the cache file from appearing in ripgrep/ag/grep search results

Rationale

The cache file is an internal file generated by projectile and should not appear in search results. This is consistent with how projectile-tags-file-name (TAGS) is already excluded by default.

Can you rebase on top of master to address the changelog conflict?

[takeokunn]

I updated!!

Seems there's a failing test now:

projectile-ignored-files returns list of ignored files
FAILED: Expected `(projectile-ignored-files)' to be `equal' to `("/path/to/project/TAGS" "/path/to/project/foo.js" "/path/to/project/bar.rb")', but instead it was `("/path/to/project/TAGS" "/path/to/project/.projectile-cache.eld" "/path/to/project/foo.js" "/path/to/project/bar.rb")' which does not match because: (proper-lists-of-different-length 4 3 ("/path/to/project/TAGS" "/path/to/project/.projectile-cache.eld" "/path/to/project/foo.js" "/path/to/project/bar.rb") ("/path/to/project/TAGS" "/path/to/project/foo.js" "/path/to/project/bar.rb") first-mismatch-at 1).

Yep, the CI is green now. Thanks!

I still see this, though:

This branch cannot be rebased due to conflicts

Probably you'll need to rebase on your branch on top of master once more and perhaps squash all commits into 1.

Resolved conflict!!
