Handle cases without localStorage for sorting

[AbdealiLoKo]

Is your feature request related to a problem? Please describe.
I was recently trying to make my browser more "secure" by locking some domains from accessing cookies etc. And I found that somehow I broke coverage's HTML report.
I was surprised, because I didn't expect coverage to need any form of storage ...
On digging further I saw that localStorage was being used to persist the sorting column

Describe the solution you'd like
If localStorage was causing an error for some reason - don't save the column that was used for sorting and just sort by the default column

Describe alternatives you've considered
Enabling localStorage for coverage is obviously an option :)
And something I'm going to do right now - but I'm not sure if its a good idea for coverage to throw an error in case it was unable to do just sorting ...
Note: If this JS error occurs, I can't do any sorting (even temporarily on this page)
