We don't allow the range control for columns to be greater than the number of images in the Gallery, but if we've set it and remove images, the columns attribute can be greater than the images. We should ensure that the columns attribute and the range control are not greater than the number of images.

Steps to reproduce

1. Add a number of image to a Tiled Gallery (8).
2. Pick a view with an adjustable columns setting (circles).
3. Set the columns to the maximum.
4. Using "Edit Gallery" from the block toolbar, remove images.
5. The images in the gallery are updated, but the maximum columns in the sidebar is not. This is the bug.
