gdata cleanup: stop passing Profile* around GData operations.

gdata cleanup: stop passing Profile* around GData operations.

After http://crosbug.com/29043 is resolved, Profile* is not used
in GData operations, except that GDataAuthService::Initialize (and
hence indirectly GDataOperationRunner) does indeed refers
to profile for OAuth2 refresh token.

BUG=none
TEST=existing tests (there should be no behavior change)

Zel, could you take a look?
These pointers to Profile are stored but are never used.
