v1.7.7: Fix 'Plus recente' = 'not connected' sur page database

Browse Source 
Les requetes MIN/MAX(timestamp) sur les tables capteur etaient
faussees par les lignes accumulees pendant le bug RTC (v1.7.4):
la chaine 'not connected' > toute date ISO en tri ASCII, donc
MAX() retournait 'not connected' au lieu de la vraie date la
plus recente.

Fix: WHERE timestamp != 'not connected' dans les requetes MIN/MAX.
Les lignes 'not connected' restent en base, elles sont juste
ignorees pour le calcul des bornes temporelles affichees.
