Fix bug #13322036 stability-sys: Java crash in com.android.settings:

android.database.sqlite.SQLiteException: malformed MATCH expression: [ avs- /y@ggmd"*] (code 1)

- the real issue was linked to the double quote
- add an InputFilter to the query EditText so that we allow only
Letters / Digits / Spaces (and this should works for all Locales)
