We should be defining the list of loggers in the controller, not the
view.

If this method was called for a file that didn't exist, we attempted to
first `build` it. But if the file wasn't writeable, such as a symlink
pointing to an unmounted filesystem, the method would just hang and
eventually timeout.

Further, this was entirely pointless since we were creating a file and
then shelling out to `tail`, eventually returning an empty Array. Now we
just skip building it and return the empty Array straight away.

This changes the style of push events that remove tags or branches so
they don't display the commit details. This prevents displaying commit
details such as:

    000000 . --broken encoding

Instead we now simply display the header such as:

    Administrator deleted branch example-branch

This is displayed in the same style as events for newly created
branches/tags.

This commit also ensures that if no commit message is present we simply
don't display anything, instead of "--broken encoding".

There might be some projects where the namespace was removed, but the
project wasn't. For these the projects still have a `namespace_id`
set. So this adds a post-deploy migration remove all projects that are
pending delete, and have a `namespace_id` that is non-existing.

mismatch in object_id between classes, disallowing params[:file], which
is a UploadedFile, newly loaded. The params checked against the older
version.
