run tests independent of user nvim setup (#39)

* chore(lua_ls): now lua_ls knows about testing functions

* spec: change way how tests srtuctured

* test(config): refactor tests

* test: utils

* refactor(utils): remove not used function

* chore(ci): add test runner

* chore(ci): remove taskfile from deps

* fix: now it works
