Revert r227148 & r227154 which added a test which infinitely loops.

r227148 added test CommandLineTest.HideUnrelatedOptionsMulti which repeatedly
outputs two following lines:

-tool: CommandLine Error: Option 'test-option-1' registered more than once!
-tool: CommandLine Error: Option 'test-option-2' registered more than once!

r227154 depends on changes from r227148
