Change order of arguments in assertion to be more logical
Change order of arguments in assertion to be more logical

Because of argument order to assert, in case of fail, we'll get message
like:

... obtained string = "uid=100(test) gid=101(test)\n"
... expected string = "uid=100(test) gid=101(test) groups=101(test)\n"

But obtained string should be second one, not the first one. And
expected string should be first. Here's sample output from test above:

... Output: before restart 'uid=100(test) gid=101(test)
', after restart 'uid=100(test) gid=101(test) groups=101(test)

It's confusing, because expected order of strings in assertion is
reversed. What goes before restart - should be "expected string" and
what goes after - should be "obtained string".
