[BUG] Single quotes in graphite dashboard are automatically replaced with double quotes, escaping doesn't work. Affects applyByNode() function. #2885

Unable to use function applyByNode(metric*,1,"function('here')") , in 3rd argument between double quotes sometimes needs to be single quote as double quotes inside double quotes cause an error. Works in main UI, but fails in dashboard (single quotes are automatically replaced with double quotes).
