Fix BP2ProviderTests

 Bug: 5142434
 For testIsValidParentWithAccount, the test would remove the account*
 from a bookmark it was inserting with a valid parent. The provider
 would correctly identify that a parent was set, but no account info and
 thus used the account info of the parent. This is not what the test was
 expecting, however, leading to this error. Fix the tests to explicitly
 check for child account* not matching parent account* (in which case the
 parent is discarded, and the bookmark is inserted at the root folder of
 the child's account*), and for testing the lack of a specified account*.
