Fix bug 2022435.
When the user clicks "install" for the TTS language pack installer and
the download completes, the addition of the corresponding package is
picked up by VoiceDataInstallerReceiver. It then causes the installer
to run by firing off the RUN_TTS_DATA_INSTALLER event.
This is less confusing for the user because the installation of the
language files is now automatic once the download is initiated. Before,
the user had to "open" the installer after the download completed.
