test: LIKE ESCAPE end-to-end tests with multiple paramters

Added end-to-end tests with different combinations of parameters inside the ESCAPE clause. like_escape uses the default analyzer while like_escape_core uses the core analyzer. Both tests contain the same test cases but use the different analyzers.
