use default values when parameters are not provided in URL

[Hagellach37]

currently there is a bug when the URL doesn't contain the values for start and end or interval.

e.g. this url https://stats.now.ohsome.org/dashboard#hashtags=missingmaps should be properly displayed and resolved to default values.

I think this issiue is not entirely solved. start/end/interval should be entire duration monthly.

as an example go to this page

• https://www.missingmaps.org/partners/morganstanley/ here you see the highest hashtag is msmapathonemea with 20622 edits. When I follow the link I want to see the same number 20622, the month it happend and the locations on the map! Which in this case is 2021-06.

@rtroilo the default range for the frontend is just the last year, so that is intended behavior currently

Still the issue is not solved, at least for me! Let me reexplain what I think the problem is.

For me the stats-frontend should have two "default-sets".

• One behavior should be that someone goes to our dashboard https://stats.now.ohsome.org/dashboard and in order to "show-case" what the dashboard is about, we prefill//prepopulate/default the parameters with hashtags=missingmaps, start/end last year and interval monthly we used the "missingmaps" hashtags, as we know there is quite same activity happening around this hashtag and so all our widgets show nice results

• The second behavior is different as someone reached our dashboard (probably from a link like the links from the missingmaps partner site e.g https://www.missingmaps.org/partners/morganstanley/) with already a certain hashtag (e.g. hashtags=msmapathonemea https://stats.now.ohsome.org/dashboard#hashtags=msmapathonemea). For this hashtag we don't know when the last activity happened (probably not in the last month) and in order to show nice results in our widget, we should have here a "different" default set which defaults to the entire-duration.
