Getting details of current player raises KeyError when no players found

[declension]

Following on from #37.

Steps

Have no players set up Ask Squeezbox what's playing

Expected

An answer without error, or at least a notice that nothing is playing (perhaps because there are no players...)

Actual

Refreshing server and player statuses...
Found 0 player(s): []
'playerid': KeyError
Traceback (most recent call last):

Same KeyError when the per settings defined DEFAULT_PLAYER is not found but another player is active.

`Refreshing server and player statuses... Found 1 player(s): ['another_player_name'] default_playerid': KeyError Traceback (most recent call last): File "/var/task/handler.py", line 37, in lambda_handler raise e ...

Propose to change the issue title to: Getting details of current player raises KeyError when no players or player(s) different from DEFAULT_PLAYER is(are) found

Thanks. Actually I've tracked that separately now (#59), it's easier as they involve slightly different solutions.
