fix(endpoint): Move endpoint_core unit test into unit-test directory

The endpoint_core's unit test needs to create a tangle-accelerator
before testing. After create a tangle-accelerator docker daemon on
buildkite agent for testing, it can be tested automatically.

Update the default port from 443 to 8000 to pass the test on buildkite.

This commit also fixes the double free error inside cipher_logger_release.

Close #669
