Fixed two IMS data profiles sent to modem

During boot up, telephony sent all available data profiles to
the modem. A regression introduced ag/18230190 caused data
profile managers created default IMS profile even when there is
already one from the database.

Fix: 233927770
Test: Able to reproduce the bug in unit test DataProfileManagerTest.
Verified the fix is working.
