Fix crash when using the magnifier

The first time that the session is started, it can happen that the
AT SPI hasn't been correctly initialized, and this results in a crash
when attempting to register the caret or focus listeners.

In order to avoid this, these changes check the result of initializing
the AT SPI, to allow further attempts when it has failed.
