 BridgesList is an overloaded field, which can cause some confusion. The
 list can be:

  1. a filter like obfs4 or meek OR
  1. can be a custom bridge

 For (1), we just pass back all bridges, the filter will occur elsewhere in
 the library. For (2) we return the bridge list as a raw stream. If length
 is greater than 5, then we know this is a custom bridge

 We should fix this so that we have separate preferences for 1 and 2. We
 also shouldn't be looking at string length to determine field type.
