When a command was picked in the "Host check command (exact match)" or "Service check command (exact match)" filter, the resulting view was always empty.

The filter compared the selected command name with the full check-command field, which also contains the command arguments (e.g. check_mk_active-http!ssl_cert!10). Since the names never equal the argument-suffixed values, no row ever matched.

The filter now matches the selected command name while ignoring the arguments, so picking a command returns the expected services or hosts.
