Sidebar Tags widget uses incorrect function to get a list of tags

[tnke]

Expected Behavior

The blog sidebar Tags widget should show all non-empty tags available on the site. You can receive a list of them by using the get_tags() function.

Current Behavior

Currently it uses the get_the_tag_list() function which only shows the tags of the first post in the current loop. From the Codex:

Generates a HTML string of the tags associated with the current post.

Steps to Reproduce

1. Add different tags to various posts
2. Go to any archive feed sidebar
3. It shows only tags from the first post in the current view

Context (Environment)

Tried to add a simple fallback archive views to a project with a full tag list in the sidebar.

Possible Solution

Change to get_tags() function. Will require some changes to the markup as well.
