Each workload has be modfied to remove the old manual paremeter conversion
and instead to retrieve the desired type from the parameter bundle directly.
Skype has a unique launch command which is called in the setup
phase of the workload. The launch command is split into a stand alone
method which can be called as a separate method if required.
This can be used as common method if more applications in future
require their own customized launch command.
Log time changed to produce epoch time in milli seconds.
Nano to milli second conversion done in uxperf result
processor is removed.
Tested on Mate8 and time obtained is verified.
Fixed contact not being found when mistakenly selecting search for
bots instead of contact.
Changed element used to determine when contact has been
selected from status indicator to search icon as with other other
contacts in view the element is never removed.
Now throws error if end call button is not found otherwise workload
could fail to start the call and incorrectly report overall success.
Since there has been an update to the skype app, there was now a
update prompt preventing test from running. Now checks for the
prompt on older versions of skype and dismisses it if present.
