Fix crash with MMI code *#06#

The code was calling getWindow().setType() on the IMEI dialog *after*
showing it.  The code had been doing that all along, but starting about a
week ago (change Iac63da) the framework now also throws an exception if
you do that :-(

Turns out there's no need to set TYPE_PRIORITY_PHONE in this case anyway,
since the dialer UI can't run on top of the keyguard in the first place
(and the contacts app doesn't have the SYSTEM_ALERT_WINDOW permission
anyway.)  So just remove the offending call.

(Note there's also a corresponding fix under apps/Phone for this same
issue.  Also, I double-checked all the *other* Window.setType() calls in
Phone and Contacts, and we don't have this same problem anywhere else.)

TESTED: Launch dialer, dial "*#06#": IMEI panel correctly comes up.
