Bug: LHS category collapsed/expanded state resets on switching teams

[harshilsharma63]

Steps to reproduce the behavior

1. Be part of more than one team.
2. Open team 1, create a category in Boards LHS and collapse it.
3. Switch to team 2, then back to team 1.
4. Notice the collapsed category is now expanded.

Expected behavior

The collapsed/expanded state of a category should not reset on switching teams. Ideally, it should even persist refreshes and be part of user's preferences.

Edition and Platform

• Edition: Mattermost Boards (plugin)
• Version: 7.2

The expand/collapse state is also lost on a simple page refresh.
