Remove &nbsp from tag pill in edit mode (#4366)

* remove &nbsp from tag pill in edit mode

PR: fix missing space between edittemplate tags #3585 introduced an unbreakable space ...

The `&nbsp` isn't needed and **causes problems**, if users copy&paste the tag text, because the "new" tag in the text input field now contains an space in front of the tag. This space invalidates the tag, so it doesn't function anymore. 

see [comment in GG](https://groups.google.com/d/msg/tiddlywiki/RQEyqPQIZSM/uaU7lgJJAAAJ) .. I also had a problem like this some time ago, which costed me several hours of debugging.

* Update base.tid

* Update tag.tid
