A problem with tests.test_simple.TestgresTests.test_simple_with_bin_dir is fixed

testgres generates the exception testgres.exceptions.ExecUtilException, but test traps the exception FileNotFoundError.

Error message is:
 Utility exited with non-zero code. Error: `bash: line 1: wrong/path/postgres: No such file or directory`
 Command: ('wrong/path/postgres --version',)
