Avoid the selection being empty in selection mode

Browse Source 
Emptying the selection with the spacebar slider puts the selection mode
in an unexpected state. This checks that this doesn't happen.

For example, moving the right end of the selection (by going right then
left in a single stroke) after it reached the left end will push it with
every steps to keep the selection of size 1.
