Fix for slow status update in mythwelcome

[bullestock@…]

Since the status update runs on a 2 second timer, mythwelcome can sometimes show an incorrect status right after exiting mythfrontend.

This patch forces a status refresh when myth_system() returns. The fix is not perfect, as the incorrect status can still be shown for half a second or so, but is is better than before.

Different issue.

I'm not sure a maximum of 2 seconds is really too long to wait for it to update though?

[bullestock@…]

No, this is not at all related to #18671.

In case I did not make myself clear the first time, let me provide a scenario:

1) My MythTV box wakes up to start a scheduled recording. MythWelcome correctly shows a status of 'recording'. 2) I start mythfrontend and cancel the recording. MythTV is now idle. 3) I exit mythfrontend. 4) Now, I expect MythWelcome to show a status of 'not recording' - but due to the (up to) 2 s delay, the status will briefly show 'recording'.

I'm not saying that this is a huge issue, but it has annoyed me more than once. And it *is* a one-line patch.

(In [19898]) Make sure MythWelcome's status messages are updated immediately after MythFrontend exits rather than waiting for the update timer to do it. Refs #6174.
