[PATCH v3 1/3] sparse-checkout: custom tab completion tests

["Lessley Dennington via GitGitGadget" <gitgitgadget@gmail.com>]

From: Lessley Dennington <lessleydennington@gmail.com>

Add tests for missing/incorrect components of custom tab completion for the
sparse-checkout command. These tests specifically highlight the following:

1. git sparse-checkout <TAB> results in an incomplete list of subcommands
(it is missing reapply and add).
2. git sparse-checkout --<TAB> does not complete the help option.
3. Options for subcommands are not tab-completable.
4. git sparse-checkout set <TAB> and git sparse-checkout add <TAB> show
both file names and directory names.

Although these tests currently fail, they will succeed with the
sparse-checkout modifications in git-completion.bash in the next commit in
this series.
