*Steps to reproduce:*
# Create a project
# Go to "Edit" -> "Project Settings"
# Select the "Tag and Layers" 
# Expand the "Tags" section
# Click "+"
# Delete by default added "New tag" name
# Observe that the "Save" button becomes disabled
# Add a space instead of a name
# Observe that the "Save" button becomes enabled
# Click it

*Actual results:* Nothing happens, just the "Save" button blinks

*Expected results:* A warning should appear, which would inform that the empty tag i is not allowed. A warning should be presented in the same way as it is implemented with the duplicated tag names.
