According to CMake policy CMP0110 whitespaces and other special
characters are forbidden before CMake 3.19. This policy is
triggered with the patch for CTest support and breaks test
generation:

NO_WRAP
The following name given to add_test() is invalid if CMP0110 is not set or
set to OLD:

  `test/box-luatest/gh_7217_repeatable_{in, up}sert_memtx_tx_conflict_test.lua´
NO_WRAP

The patch renames file without using whitespaces and special
characters.

Required for CTest support. Follows up commit 654cf498
("memtx: fix story delete statement list").
