bachinger c4171d50cc Remove MediaSourceList.maybeThrowSourceInfoRefreshError
The method has been called from two call sites in EPII triggered by EPII.updatePeriods(). The first call site was calling it when the MediaSourceList is empty or not yet prepared. This can be removed because if empty or not prepared no source ever could have thrown yet.

The second call site was checking for potential source refresh exceptions when queue.getNextMediaPeriodInfo() returns null when trying to getting the next loading period. Looking into all reasons for why the method returns null, none of them is caused by an exception of a media source. The reasons are:

- if we are at the last period of the timeline
- if the defaultPosition of the next period in the timeline is null (if the window.durationUs == C.TIME_UNSET or defaultPositionProjectionUs is projected beyond the duration of the window)
- if we are waiting for an ad uri to arrive (period.isAdAvailable(...) == false)
- if we are waiting for the ad group count to be updated (adCountInCurrentAdGroup == C.LENGTH_UNSET)

The above reasons are not caused by a source error and may be resolved when doSomeWork is called the next time. Hence it is save to remove the calls to maybeThrowSourceInfoRefreshError().

Beside this, an actual sourceInfoRefreshError will be reported by maskingMediaSource.maybeThrowPrepareError(), which is called each time doSomeWork() is called and the playing period is not yet prepared (EPII:L836). So the player is notified by source errors that way, which confirms removing the above calls is fine.
