Build cache not consistent with globs

[jmorrell]

Copied from a support ticket:

Our node app contains the following lines in the package.json:

  "cacheDirectories": [
    "node_modules",
    "browser/node_modules",
    "node/*/node_modules"
  ],

As you can see, we use a glob to specify which folder need to be cached. At the end of the build process we see what we expect:

Clearing previous node cache
Saving N cacheDirectories (package.json):
- node_modules
- browser/node_modules
- node/foo/node_modules
- node/bar/node_modules
- node/baz/node_modules

But when the build starts, and the cached directory are loaded, where is what we see:

│remote: -----> Restoring cache
│remote:        Loading 3 from cacheDirectories (package.json):
│remote:        - node_modules
│remote:        - browser/node_modules
│remote:        - node/*/node_modules (not cached - skipping)

We would expect that the same strategy is applied when restoring the cache (using glob matching in the cached directory).
