Fix for Bug 403: Install button does not work correctly first time if flow is edited in UI.

Root Cause: Whenever user edits a flow entry, page.js file passes the value of installInHw as true always (line ). If the flow is not installed in the hardware, this reverts the value of installInHw from false to true causing this issue.

Fix: Changes Done:
1. In page.js file, On edit click button a new variable install is defined, which is assigned to the value of installInHw(true/false) in respect to a flow entry.
2. The variable install is passed to the edit function instead of passing the value as true always
