Update deprecated IdentityServicesProvider function in password manager.

This CL replaces deprecated functions of IdentityServicesProvider with
the newer service getters with profile parameter.This CL passes
|Profile#getLastUsedRegularProfile| to |getIdentityManager| function.
Using always regular profile is safe, since code block is only called
for regular profile, while there is no plan to be called for
off-the-record profile.
