Fixed FreeMarker template resolution issue when OFBiz installation or component paths contain spaces (OFBIZ-10434) (#1226)

Updated FlexibleTemplateLoader#getURL() in FreeMarkerWorker to use: 
`new File(locationUrl.toURI()).exists()`
This fixes template lookup failures caused by URL-encoded paths (%20)
when OFBiz or component directories contain spaces.

Thanks Jacques Le Roux for reporting the issue.
