Update deprecated IdentityServicesProvider function in PickerAdapter.

This CL replaces deprecated |IdentityServiceProvider#getIdentityManager|
with the newer getter with profile parameter. PickerAdapter provides
contacts for contacts picker by using email info coming from identity
manager. Since this is read only operation, this CL always passes
|Profile#getLastUsedRegularProfile| to be able to provide contacts
information even in incognito mode.

Note: This is only clean up and does not change any code behaviour.
