Multiple file exist checks for one file during declarative view creation slowing app startup.

During qml app startup, one qml file may be checked for existance couple of times. This happens when:
1. Item defined one qml file is used in other qml files - for one file one check is performed.
2. When java script element is used in qml file - usage looks like this:

import "Logic.js" as Logic
Log file shows, that during declarative view construction there are 18 checks of file Logic.qml existance - there is no Logic.qml file in app, only Logic.js.

On symbian platform file exist check are time consuming, so making multiple checks of the same file may slow app startup considerably. Also there are unnecessary checks made for file that doesn't exist (Logic.qml when there is only Logic.js file present).

Log attached.
