Use AT_MOST for label when photo is on right

In I269175d9dea97baa86bcb1badc9e6294dcb7883b we introduced EXACTLY,
since AT_MOST requires more calculation and thus made the contacts
listing slower.

In picker screens, however, we need that for email/phone types because
of its layout requirement. This change introduces AT_MOST only in that
exact case, so that it won't cause any performance regression in our
major cases.
