Subject: [PATCH 1/2] fix: parse the binary path emitted by the test build task

`strip_prefix("-femit-bin=")` already returns the bare path, so the following
`split("=").nth(1)` only produced a value when the path itself contained a `=`.
Everywhere else it returned `None`, so the locator failed with "None of the
locators for task `zig test --test-no-exec` completed successfully" and
debugging a test was impossible.

Subject: [PATCH 2/2] fix: strip quotes from the --test-filter argument

The build task is spawned directly rather than through a shell, so the quotes
wrapping $ZED_CUSTOM_ZIG_TEST_NAME in the zig-test task template end up inside
the filter string. `zig test --test-filter "'demo'"` reports "All 0 tests
passed", so the debug session launched a binary containing no tests and exited
immediately. Each argument is already a single argv element, so no quoting is
needed.
