FIX: Automatically recover from bad sprockets cache in development (#8364)

Browse Source 
We were having issues in development mode where the JS code had errors due to a bad cache. When starting a server in development mode in bin/unicorn we now get the git sha of the discourse HEAD and get a git sha of all plugins, and store them in a file. If the sha has changed then we delete tmp/cache to refresh the assets cache.
