Problem description

Check the issue.

Problems:

• html tags select with option cannot have an image: https://stackoverflow.com/questions/32068127/angular-select-with-images and there is missing searching feature, so I replaced the select with ng-select
• placeholder wasn't working in the ng-select, it was because the initial value must be null for the ngModel mapped into ng-select.
• NOTE: everytime after installing 3rd-party framework into DSpace try to remove all node_modules with yarn.lock and run command yarn install. It helps you to discover dependency error which you probably will discover by the Github action what is very time consuming discovery. That is the reason why I was forced to remove ng-select from the DSpace project, because that lovely module destroyed whole project, I was trying to make the dependencies compatible but without any success.
• After disaster with ng-select I was trying to find any 3rd party module which won't destroy whole project but without any success, so I decided to create our own a new license selector, which I developed here: migration2clarin7/license-dropdown-missing-labels-2 #164
