Plugin install hangs if URL returns a 404

[cp2004]

What were you doing?

1. Install plugin from URL, eg:

https://github.com/cp2004/OctoPrint-EEPROM-Marlin/archive/3.0.0r3.zip

which should be

https://github.com/cp2004/OctoPrint-EEPROM-Marlin/archive/3.0.0rc3.zip

but there is a typo.

What did you expect to happen?

Error was reported to the user

What happened instead?

Unhandled exception in plugin manager thread, and install window hangs:

Did the same happen when running OctoPrint in safe mode?

Unable to test, since plugin install is not possible under safe mode.

I have read the FAQ.

In addition (and it might be related) the undervoltage state is not reported to the frontend, maybe it is related to #3849

[kantlivelong]

Submitted #3889

[foosel]

Thank for that, merged to maintenance and ready for 1.6.0

[cp2004]

1.5.3 has been released

Consider me mightily puzzled whether this actually made it into 1.5.3 just now and thus a milestone set/reset storm.
