* The PduPersister had some code where it checked uris for
equality, but didn't use the safe .equals method.
Test: manual test of sending and receiving mms's.

This bug and AOSP patch arrived last July. Supposedly, I
merged the change, but it's certainly not fixed in bugler, nor in various
copies of PduPersister in Android's master. Fixing all the locations
now.
Test: manual - sent/received MMS's to verify the change didn't break
existing behavior.
