Show error message on trying to delete last dashboard

[johannaengland]

This is not an actual bug, but something I noticed when working on #3150.

The "Delete dashboard" button is already not shown when there is only one dashboard, so it is not possible for a user to try to delete their last dashboard.

So to reproduce this you need to change this line to actually show that button:

nav/python/nav/web/templates/webfront/index.html

Line 147 in 27b12b5

{% if request.account.account_dashboards.count > 1 %}

After that when trying to delete the last dashboard an alert box will be added with the content [Object object] instead of showing the correct error message Cannot delete last dashboard.

I rescind my earlier approval, i still get the [object Object] message when trying to delete

Could this be some javascript shenanigans?

[stveit]

Yeah nevermind, just my js scripts werent updated. Had to down-up the containers and now it works fine
