Expansion: Fix crashes when opening UART apps with serial module connected

[zcbml88]

Describe the bug.

When I open subghz or frequency analyzer, flipper crashes and says "flipper crashed but has been rebooted applications/services/expansion/expansion.c" and reboots then crashes again, then sometimes reboots with all glithed out screen saying click back button for factory reset.

Reproduction

Open subghz folder, then open frequency analyzer, scroll up,up,down,down,down,down.

known issue, being worked on in flipperdevices/flipperzero-firmware#3429. for now, set Settings > Expansion Modules > Listen UART = None and Settings > System > Log Level = None to fix this.

for context, the issue is copious amounts of serial feedback from a connected UART based board confusing the expansion module listener. disconnecting your wifi module (or whatever else it is) would equally fix the issue.

as for

then sometimes reboots with all glithed out screen saying click back button for factory reset.

that is something weird you are doing on your own, pressing random buttons.

fully fixed as of merging the above mentioned PR via fe22543 from what i can tell, i cannot get it to happen again in any way no matter how hard i try. reopening as this is still an issue in release, will close when the fix is in a public release. for now, try the dev builds (i will issue one soon, have to change a few more things first)
