UI: Fixed many automation issues

1) for config-template and hostgroups, location context associates all the templates and hostgroups by default to a newly created to location.
2) Hence association of templates and hostgroups could fail and hence the needed fix.
3) Also added 2 new test-cases to make sure that for configtemplate and hostgroup the "All values" is selected by default.
4) Marked few testcases to be skipped by BZ.
