Dependancies have broken autocomplete of their JSX props

[Lomand]

Hi,

For some reason jsx props of external dependancies are not displayed when pressing Ctrl-Space.

Meanwhile local components do not suffer from this issue:

@Lomand thanks for the report.
Turns out, this has not do do with dependencies, but with when components are declared as external (#308).
