tests: Add more tests for branch coverage

gcov -b surfaced many lines with partial coverage, where branch is only
ever taken or not taken, or one of the expressions in a complex
conditional is always either true or false. This change adds a series of
tests (mostly focusing on XPath) to reduce the number of partially
covered lines.
