Fix test failure because of duplicates file templates in classpath

There're two ways for getting templates in test runtime. One is from
sources resource files, the second one is from compiled jar.

Remove the first entry manually.

A better fix is to extract tests to separate module. This will leave
only jar in the test runtime classpath.
