discarding history does not remove darktable|style tags from image

[ralfbrown]

Describe the bug

The code for dt_history_delete_on_image_ext in src/common/history.c intends to remove all style tags from the image, but fails to do so because it passes a string with a wildcard to a function which only does an exact match (and could only handle a single match even if it supported wildcards).

Steps to reproduce

1. apply one or more styles to an image
2. have both the history stack and tagging modules open
3. enable display of darktable tags in the tagging module
4. select the image, then use discard history
5. hover over the image and note that the style tag(s) are still displayed in the tagging module

Expected behavior

the style tags should be removed since they no longer apply to the image
