When using an editable map is better to load marker latitude, longitude and
map zoom from form fields so we can show the marker at latest position defined
by user when the page was restored from browser history.
To reproduce this behavior:
0. Undo this commit
1. Go to new proposal page
2. Place the proposal map marker
3. Go away to any other page
4. Restore new proposal page from browser history.
At this point you should not see the recently placed marker.
The same thing happens when editing a proposal.
If we do not do this a map could be initialized twice times or more
when restoring a page with a map causing weird UI effects and
loading some map layers also twice times or more.
Need to add a maps array to be able to store all initialized
(visible) maps so we can destroy them when needed. Notice that
we are destroying maps also when admin settings tabs changes
(only visible ones), this is again to avoid to re-initialize map more
than once when users navigate through settings tabs, another
option to the settings issue could be to detect if the map was
already initialized to skip uneeded initialization.
We were submitting the form without checking the AJAX request to attach
the image had finished, so sometimes two requests were executed at the
same time. Sometimes this made InvisibleCaptcha to go crazy and report
the form was submitted too quickly.
Checking the first AJAX request has finished before submitting the form
solves the problem.
We were checking `expect_document_has_title(0, "My Title")`, which was
already true before the AJAX request generated by `attach_file` had
finished.
That meant the AJAX request sometimes was handled after this test had
finished, affecting the following test and causing it to fail because
its cookie was overwritten and so `current_user` was set to `nil`.
In the test checking the filename is present, a similar scenario was
taking place: we were updating the `.file-name` element in the `change`
event of `fileupload` (using `App.Documentable.setFilename`); that is,
when the AJAX request started. And so the test passed before the request
was finished, causing the same issue.
