Upload Perfetto Trace and Screen Recording as Unique Files when

recording an issue.

This is part of the RecordIssueTile. These files are not all openable
within solely the winscope web ui. Particularly, the perfetto file is
not useful in winscope, but has it's own ui. The screen recording
likewise can individually be opened in buganizer without the need to
pull all traces into winscope.

Also fixed issue where crash would happen if traces.get was null
(which happens if share notification is clicked more than once).
