Show Nummer of entries behind every suggested tag

[wellemut]

User Story: As a User I want to see how man results I get when choosing a tag in order to better know, which tags I should browse or use for tagging new entries.

Problem:

• people have no indication how many entries they choose find on the map
• browsing an empty place might make leave users, if they have no hint that the are more results somewhere

Solution(s)

• [ ] A. Show the number of search results behind each tag which is suggested to the user while searching and while mapping
• [ ] use the existing API https://www.kartevonmorgen.org/api/v0/entries/most-popular-tags?contains=deme
