[PATCH] test: Always use paths without symlinks

[Michal Sojka]

When notmuch sources are at a symlinked path, some tests fail because
one part of the test uses physical path and another uses logical
path (with symlinks). For example the following test output is
produced when the test is started from /home/src/symlink-to-notmuch,
which is a symlink to /home/src/notmuch.

This commit makes all paths in test scripts physical. With it, all
tests pass even when run from a symlinked directory.
