add tests for yaml-pro-ts-* functions

[rodrigomorales1]

The introduced tests can be run by executing the following command in the root directory of the project.

emacs -batch \ -l ert \ -l yaml-pro-edit.el \ -l yaml-pro.el \ -l tests/yaml-pro-ts.el \ -f ert-run-tests-batch-and-exit

NOTE: In the future, I'm planning to add more tests. First, I've written these simple tests so @zkry (creator of this project) can confirm that this is correct behavior. Then, I'll write more complex tests.

Here's proof that these tests run successfully:

$ emacs -batch -l ert -l yaml-pro-edit.el -l yaml-pro.el -l tests/yaml-pro-ts.el -f ert-run-tests-batch-and-exit

In the last two commits 17be0a1 and 52514bd. I've introduced changes to modify behavior in yaml-pro-ts-meta-return in some scenarios. Please see minimal working examples below. The examples are the same from those of the introduced tests.

1. test-yaml-pro-ts-meta-return
2. test-yaml-pro-ts-meta-return-trailing-newline
3. test-yaml-pro-ts-meta-return-trailing-newline-list

test-yaml-pro-ts-meta-return

(yaml-test-with-temp-text "- 1: one<point>\n"
  (yaml-pro-ts-meta-return)
  (buffer-substring-no-properties (point-min) (point-max)))

In the latest commit 7f2b344, I've introduced changes to yaml-pro-ts-move-subtree to improve its behavior when the file has a trailing newline at the end. I also added some tests. Please see minimal working examples below (the examples are the same from those of the tests).

1. test-yaml-pro-ts-move-subtree-down-point-beginning-of-line
2. test-yaml-pro-ts-move-subtree-down-point-end-of-line
3. test-yaml-pro-ts-move-subtree-down-no-trailing-newline
4. test-yaml-pro-ts-move-subtree-down-trailing-newline

test-yaml-pro-ts-move-subtree-down-point-beginning-of-line

(yaml-test-with-temp-text (concat
                           "<point>1:\n"
                           "  1.1: null\n"
                           "2:\n"
                           "  2.1: null\n"
                           "3:\n"
                           "  3.1: null\n")
  (yaml-pro-ts-move-subtree-down)
  (buffer-substring-no-properties
   (point-min)
   (point-max)))

Both versions produce the same result
