fb: actually fix LTE toggle (1/2)

I accidentally pushed the LTE toggle patch although it was not ready.
Whatever here the fix for it. This commit does:

- do not assume that on boot ITelephony service is already up. This
  results in a FC on boot up
- handle like before most things in LTETile itself and call only
  the toggle action to prevend above mentioned
- I thought about it to give as parameter current network state
  to the toggle method to prevend to fetch 2 times the actual mode
  (saves 4 lines of code). But based on the idea that we maybe later
  use other shortcuts as well we will not do it.
- cleanup & codestyle

Sorry again

cheers

WiFi label is not a Quote!

Cleanup the damn quotes around the WiFi label in the
notification panel. This only removes the quotes from the first
and last positions of the string.

PS 2 : WiFi name can have quotes!

Fix preference puts with "null" values.

Null values were being written out as <null /> elements in the
XML prefs file (as expected). This allowed the getFoo() functions
to work correctly because they treated null values as missing mappings
but containsKey would fail.

MountService listeners can not be unregistered

When unregistering MountService listeners, their Binder proxy
objects were compared to registered listeners instead of their
backing objects.

Add NULL check in updateProxyConfig

If the exclusionList was null in updateProxyConfig the VM would
crash when converting it to a UTF8 string. Avoid this by adding a
null check.

Before requerying a cursor, check if it is closed.

Before updating a cursor,
it needs to be checked if it is valid.
Currently a defence code only checks
if it is not null.
But in case of "Cursor", it is not valid,
if it is closed.
So just like in CursorAdapter.onContentChanged(),
add the additional defence code to check validation.
