[MOS-663] Regression fix

Fixed a regression that the SMS template list showed always
the state representing no templates defined, regardless if
there were any in the database.

refreshing the window is doubled which can be seen in
debugging, but it's unnoticeable in usage.

[MOS-176] Fix long turn off time

Fix of the issue that resulted in long
turn off time of the phone, which was
caused by unfortunate coincidence
of functions names - as a result the
one from the included header file was
called instead of the one from the
anonymous namespace inside the file,
what resulted on not cutting off
board power until the watchdog
triggered.
