MemTableFactory creation failed: Not implemented: Could not load MemTableRepFactory: ('speedb.HashSpdRepFactory',)

TEST FAILED. See kill option and exit code above!!!

The reason is a bug on my part when I added the choice between the skip list memtable and the Speed one and accidentally added a comma to the end of the line, which was later formatted by black with a proper tuple construction.

To Reproduce

make crash_test

Expected behavior

The test doesn't crash because of the choice of memtable.

System (please complete the following information)

• OS: Ubuntu 20.04
• Compiler and version: GCC 9.4.0
