This printed a table. This will make Lua print the address of the table and
hence the output of this test was non-deterministic.

There was a problem that the examples were considered to have failed as soon as
they produced any kind of output, but there were legitimate cases of warnings
being printed that triggered these checks. Commit 4819be4f4f used a
regular expression to detect and ignore this warnings.
This commit reverts the above commit and instead silences the warnings by
monkey-patching the function that prints the warnings into a no-op.

The requirement to call add_signal() was added to catch typos. However, this
requirement became increasingly annoying with property::<name> signals and e.g.
gears.object allowing arbitrary properties to be changed.
All of this ended up in a single commit because tests/examples fails if I first
let add_signal() emit a deprecation warning.
