WXGUI identify tool on vector layer triggers map canvas rendering even if it's disabled

[marisn]

Steps to reproduce:

• add some vector and raster maps
• disable rendering in map display
• change visibility of map layers in the layer manager and DO NOT refresh map display
• use identify tool on some vector object

Map display contents are refreshed and canvas content will represent current map layer visibility etc. still automatic rendering is still disabled and shouldn't happen unless requested by "Display map" or "Re-render map" tools.

Should be fixed in all branches (r52879, r52880, r52881). After testing please close ticket if it's ok.
