This fixes an issue where Steam OTP's were displayed in the wrong
format. The underlying issue has been present for a while, but it first
became apparent in e4c9a584f4.
Fixes#975
And display "ERROR" for any existing bad entries. This is kind of ugly,
but it's better than crashing, and there are probably very few (or zero)
users who have bad entries anyway.
The conversion of the OTP period value to milliseconds may overflow for large
values, causing the result to wrap around to Integer.MIN_VALUE. This
subsequently caused a crash when calling ObjectAnimator.setDuration.
