Only bare-identifier imports (`using Foo`) emitted edges. tree-sitter-julia
wraps qualified paths in `scoped_identifier` (`using Base.Threads`), relative
paths in `import_path` (`using ..Sibling`), and the package of a
`selected_import` may itself be a `scoped_identifier`
(`import Base.Threads: nthreads`). None of those were matched, so qualified and
relative imports were silently dropped, and scoped selected-imports pointed at
the selected symbol instead of the module.
Resolve the module name from identifier / scoped_identifier / import_path in
all three positions. Adds fixture lines + a regression test.
