test: port previously-ignored Composer tests via __ test hatches

Re-evaluate the reason'd #[ignore] tests under the Phase D criterion:
a test is unportable ONLY if the APIs/types needed to WRITE it do not
exist. A test that compiles but panics at runtime (todo!() body, a
regex the regex crate cannot compile) or fails at runtime (incomplete
or incorrect impl behavior) is portable -- it is written in full and
marked with a reason-less #[ignore].

About 120 test functions move from reason'd #[ignore] to reason-less
#[ignore] (the ported-but-not-yet-passing signal). Impl crates gain
only additive __ test hatches (init_command, pool, file_downloader,
package handle link setters, artifact/path repository, repository
manager, svn); no existing logic changes. Tests whose required APIs
genuinely do not exist (mock/reflection harness, ApplicationTester,
solve() discarding SolverProblemsException, a script::Event that
cannot be passed as an originating event) keep their reason'd
#[ignore].

cargo check -p shirabe --tests passes.
