Fix downtime check formatting

## What does this MR do?

This MR adjusts the formatting of the migration downtime checker so messages are more readable.

table must not change while this is running, so downtime is required.

This removes excessive whitespace from the messages (e.g. leading
whitespace) and ensures the message is more clearly visible.

These JS errors are only thrown in PhantomJS, and enough of the page is
rendered properly that this spec passes. We should remove this in
future.

The colours were incorrect: offline was green and online was red,
instead of the opposite.

Don't show comment button in gutter of diffs on MR discussion tab

When browsing to an MR, switching to the Changes tab, and switching back to the Discussions tab, the gutter of the diffs on that page would show the comment button on-hover, while it shouldn't, since comments on new lines can only be created from the Changes tab.
