UltiSnips-add-snippets in :help section is missing

[foo-dogsquared]

This issue is quite similar to #1033 but with the different section. There's a missing topic/section UltiSnips-add-snippets in the help section 3.4.1 of the plugin.

Expected behavior: Should be given a help panel.

Actual behavior: E149. No help section with the given section (UltiSnips-add-snippets).

Steps to reproduce

1. :h UltiSnips-add-snippets
2. Error should be given at that point

An alternative: 1.:h UltiSnips 2. /UltiSnips-add-snippets 3. There should be only one search match.
