Change supportsStop to supportsStopTilt

[iMicknl]

Proposed change

Since a recent update, the controls for a cover with only tilt features are partially broken. The stop button is not present anymore since a recent update. This is due to the fact that front-end checks for supportsStop instead of supportsStopTilt. This is the wrong feature from supported_features, since it is not related to the tilt controls.
