Pull request #5969 fixed the vertical alignment of loading icon and
status message in Theming app, but in doing so it broke the loading icon
inside the upload button.
When an image is being uploaded the upload icon is replaced by a loading
icon, so the loading icon and the upload icon have to share their CSS
rules, but only in that specific case.

As both elements are inline/inline-block and belong to the same line
they can be aligned vertically using "vertical-align: middle".

The loading icon is used in a totally different way than the upload icon
and thus it should not share its CSS rules.

The removed rules were either always overriden by other rules or never
used due to not matching any element.
