js: clean up test extension

--

Tests will now run with one instance of gpgmejs each block,
which reduces overhead. Readability is (hopefully) improved),
some negative tests are added.

There is still a performance problem in base64 encoding/decoding,
which causes some tests to fail due to time out.
