Bug: in case of streams that had no logs in a given time range all streams are returned.

[pwilczynskiclearcode]

I've got streams called a-1, a-2 and using:

awslogs get -s 1m application/run.log a-1

returns all application/run.log logs.

And if I change it to

awslogs get -s 10m application/run.log a-1

Only logs from a-1 are returned.

It seems that awslogs or boto/AWS returns all logs if stream regexp doesn't mach any entries.

I ran into this the other day. was very confused by the behavior. Good to know I'm not crazy.
