Fix unexpected rotation change when re-enabling auto-rotate

Change-Id: I829b156e85b755e75c2168f877bffa0468969a20
Function uri.getAuthority is called twice. Minor doc corrections.

Function uri.getAuthority was called twice in methods acquireProvider
and acquireExistingProvider was called twice although a parameter
representing the value had existed. The second call to the function is
changed to the parameter. The parameter's modifier changed to final.
Minor corrections in function descriptions in the file.

Change default intent

Older JB releases have a bug handling persistence invocation. One work
around right now is to have the newer release (with persistence)
use  a lower intent value to allow older release to operate in group
owner mode.
