Material UI theme provokes FTA-FMEA to crash

[LaChope]

NOTE: #343 might solve this issue, but #365 must be completed first to be able to test the fix.

@blcham @Kasmadei
On both the development server and dockerized version, app crashes with:

Firefox error:

Chrome error:

The issue comes very probably from the changes of this commit.

#309 fixes part of it. When using internal auth, it works when loading the app for the first time, but if you refresh (also CTRL + F5), app crashed with the same error as above. This behavior occurs even after 155a79d and 09517db, we just did not try to refresh page before.

I tried to remove all useTheme hooks from all files, but the issue still occurs.

Reopening as not completed (see comment just above)

It might be little relevant to: kbss-cvut/record-manager-ui#125 (comment)

[blcham]

@LaChope what do you propose to do with this? Should we put it to TODO ?

[LaChope]

Yes, also I am updating the description as #365 should be completed before this.

[blcham]

@LaChope I guess this is not relevant for the delivery -- putting it into "technical debt sprint"

[LaChope]

@blcham yes
