Mms: sets endMmsConnectivity() as last operation

When a user receives an Mms and there is no more pending requests, the method
endMmsConnectivity() is called to turn the data connection off and clear the
wakelock. Sometimes the phone deep sleeps before the user gets Mms
notifications, so this patch makes endMmsConnectivity() to be the last
operation so users can be notified of Mms's.

Mms: switch inverted text color back

it is not consistent that the sender text is now
holo light blue dues that the entered text from
the user is white. Switch it back to old behaviour
so entered text color is the same like senders color
and received sms color back to holo light blue
