Pass ComponentName to probing certificate methods

Pass ComponentName and check whether that admin is a profile owner on DPM
get/has certificate methods (requested on the API review).

As per Change I55eec17e01489ab323f8a0e68b11592605a7b740, not keeping track of
which admins installed which certificates for now:

"Having per-admin CA certificates would be a fair bit of work. The only MDMs
we're opening this up to for now are Device and Profile Owners which 100%
manage the profile so will be the only admin.
It seems like if we keep track of "who installed which certs" it'll be a little
pointless because the answer will always be "the ProfileOwner" for every single
one."
