Add some component path canonicalization tests

Previously, no unit test existed to ensure that url canonicalization
worked correctly, which could result in two import statements using
relative paths to the same actual component triggering two separate
types being generated.

This commit adds a unit test with various relative-addressing and both
static and dynamic imports, to enforce type-consistency.
