bachinger 1c8c563263 Do not reset period uid when DashMediaSource is released
When the source is prepared again after stop, the period uid
is calculated by subtracting the `firstPeriodId` from the
period uid that is passed in to `createPeriod`. When this
happens after stop, the uid from the old period uid that
is still stored and has the value of the last played uid.

Hence the `firstPeriodId` must not be reset when released.
