Attempt to fix match leaks #110

Hello,

I got notices of "matches" accumulating while using another library [1] using this library for dbus communication. Traced it until MessageBus._addMatch/MessageBus._removeMatch which seems to get called properly. However, the dbus messages AddMatch and RemoveMatch does not. That is, I could not observe a RemoveMatch message for every AddMatch message.

This PR attempts to correct the property check on the counter. Should be the same as this._matchRules.hasOwnProperty(match) as far as I can see.

For my test case the proper RemoveMatch messages get sent as well after this change.

I didn't have a deeper look at the logic. If not the proper solution, maybe it can serve as a description of the issue :)

Attempts to correct logic to intended behaviour. That is,
check existing property `match` on `this._matchRules` instead
of `this._matchRules` on `match`.
