Search map without current position marker

[Phyks]

When going back from station details to search map, the current position marker is not there anymore.

Actually it is because we are in a "search station" view, see issue #90.

For me the icon of the position marker is always broken.
But the fact that it completely disappear is another issue, indeed.

Broken position marker was fixed today, see another issue :)

Ah ok =)

[Phyks]

@eliemichel should be fixed. We should check there is no memory leak.

@Phyks please try to always link the issue to the commit solving it.
I you forgot to include "Fix #97" in the body of the commit, which would also automatically close the issue, just give the small hash of the commit in the closing comment.
