Current location does not appear in Trips when allowing geolocation

[mlbiche]

As mentioned in commit 940f8ba995ddf885e65b10aecdd90220e04dbd5e :

Note that if the user directly navigates to Trips before allowing geolocation, his current location won't appear once he allows it. It will only appear on refresh.

It could be fixed by editing the previous current location marker in the map to turn it into a normal trip point, adding the new current location marker and moving map to adapt to new markers' bounds. It seems not a high priority issue IMO.
