search by location+refresh blocks panning

[pvgenuchten]

I can not reproduce this on vanilla geonetwork, so i guess it is related to dutch view (locatieserver search).

Reproduce by:

• load a dutch map in epsg:28992 in a clean browser
• notice that panning works fine
• zoom to an address (with location search)
• refresh the page (f5)
• try to pan to other side of country
  -> the map prevents panning outside the initial location found with the search control

the problem is in restoring the map after refresh of the page.
i can reproduce strange behaviour also on vanilla by:

• zoom to paris
• refresh page
• pan a little
• refresh page
  -> map is broken (white)

Even worse, after only 2 refreshes the map is broken. To restore the map it's necessary to use the "Default map" button in "Manage layers" panel.
