For some reason, the unit tests for Deno.remove() were not being imported to unit_tests.ts and, consequently, not being executed. Thus, I imported them, refactored some existent ones and wrote new ones for the symlink removal case. Since the creation of a symlink is not implemented for Windows yet, assertions that consider this state were added when the tests are executed in this OS.
