Fix the missing remove-link UI in protocol handler settings

Fix the missing remove-link UI in protocol handler settings

A previous CL (https://codereview.chromium.org/518673003/)
that introduced policy indicators for protocol handlers
introduced a bug that results in remove-link option not
being shown on protocol handler settings. The problem is
caused by a variable name being replaced in the last
minute. All occurrences of the variables were not replaced,
resulting in the problem. This CL replaces all occurrences
of the variable.
