[PATCH] bluetooth-policy: retain backwards compatibility

[tanuk@xxxxxx (Tanu Kaskinen)]

The auto_switch argument was added in PulseAudio 10.0. In that release
the argument type was boolean. The type was changed to integer in commit
3397127f00. This patch adds backwards compatibility so that old
configuration files won't break when upgrading PulseAudio to 11.0.
