Description

Disable the button "Ny statusrapport" when a report is unpublished. Also when navigating between other reports while having an unpublished report.

How to test:

• 1. Create a new report.
• 2. The button "Ny statusrapport" will stay disabled until you publish the report.
• 3. The button will also be disabled if you navigate between other reports while having an unpublished report
• 4. Create a new report and the button should be disabeled once again
• 5. Select an older published report.
• 6. Verify that the button "Ny statusrapport" stays disabled

Not trying to be a critic here, but this is not so intuitive imho

!!data.reports.filter((report) => report.moderationStatus.indexOf("Publisert")).length

A filter callback should return true or false. This will return -1 or the index of "Publisert", so I'm not sure how this filter function will work?

If the filtered array returns 0 for length this will yield !!0, if the length is 2 it will yield !!2.

Skal denne PR tagges mot 1.2.3 og ikke 1.3 som det står nå?

Viktigste er vel at issues kobles mot riktig milepæl.

Var feilsatt, har oppdatert nå med conditional operator som det jeg begynte på.

Looks good!

Tested in console, and seems to work just fine!
