Description of problem:
When trying to search for a package in a life-cycle environment, after typing some string (say bind*) and pressing Enter, one would expect the bind* packages to be shown. Instead of that, search is cancelled and all packages are shown. That misinterprets user thinking there is no such package.


Version-Release number of selected component (if applicable):
6.1.8


How reproducible:
100%


Steps to Reproduce:
1. WebUI: Content -> Lifecycle Environments -> Click to Library -> Packages
2. Type in Search field bind*
3. Click to Search button
4. Type there again bind*
5. Press Enter instead of clicking to Search button


Actual results:
3. shows ssh packages, having the search string the entered one
5. shows all packages, search string is empty, like cancel/reset of search


Expected results:
5. to behave like 3. does
