Fix FeedbackActivity NPE

[jaredsburrows]

Issue:

mInitialAttachments in FeedbackActivity is not initialized. Instead of checking, let's make sure it is always non-null.

Error:

java.lang.NullPointerException: Attempt to invoke interface method 'boolean java.util.List.removeAll(java.util.Collection)' on a null object reference
