Fix GTest Death Style Tests and LoadDirectory test in conda (#5469)

- GTest Death Style Tests clone the current process but don't follow
  the PATH to discover the executed binary. As in conda, we use
  relative path and the tests are installed in bin this fails. This
  change makes sure that tests are invoked with the full path specified.
- LoadDirectory tests assume that the plugins are located next to the
  test binary while in conda they are copied to the global lib dir. This
  PR accounts for that.

Fix PaddlePaddle plugin docs (#5276)

PaddlePaddle plugin docs (API reference) were rendered empty, because a version check in paddle.py failed when paddle was sphinx mock module instead of real one.

In this PR I skip this version check if no string version of paddle is present.
