Fix main-kts jsr223 direct bindings processing

Before the jsr context was configured only when a dependency or import
annotation is encountered, so direct properties mapping didn't work
without using any of the annotations. (It was implemented like this
as a workaround due to the problem with handlers composability, that was
fixed some time ago.)
