Modules: removed extra VMs creation when it is not needed.

Previously, a new VM instance was created for every location. This is
not needed and consumes a lot of memory for large configurations.
Instead, if no new js_import is introduced on the location level server
level VM should be used.

The issue was introduced in 9b674412 (0.8.6).

This fixes #795 issue on Github.
