clang-format: Fix incorrect indentation.

Before:
aaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbb.ccccccccccccccccc(
               dddddddddddddddddddddddddddddd));
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(
    dddddddddddddddddddddddddddddd));

After:
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbb.ccccccccccccccccc(
    dddddddddddddddddddddddddddddd));
aaaaaaaaaaa(bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb(
    dddddddddddddddddddddddddddddd));

This was overlooked when interducing the new builder-type call
detection in r189337. Also, some minor reorganization of a test.
