Fix permission checks for non admin users

[edmundoa]

Some components were using wrong permission values in checks, so non-admin users could never get to do those actions.

Original issue: #2358

The changes should also be merged into 2.0, I already checked they apply cleanly.

Could you please replace the {this.isPermitted(...) && pattern with usages of the <IfPermitted /> component? Makes the code much more readable and maintainable imo.

Sure thing, I was looking so much into writing the right permissions that I didn't even look at that 👍

I have replaced most of the isPermitted in touched files with IfPermitted. I found some issues doing so in the navigation bar dropdown, as IfPermitted is swallowing additional props that react-bootstrap is giving to it.

We could clone the children elements given to IfPermitted to pass the props down, but I don't feel confident on doing so if the changes are going to 2.0.3, as we don't know if they affect other components or have any performance impact. I'm willing to make that change in master afterwards, as we can see the impact in a longer term. How does that sound?
