fix(test): use getProjectPath in sessionScanner test for consistent path calculation

The test was failing because it manually calculated the project directory path
by only replacing `/` with `-`, while getProjectPath replaces additional
characters including underscores. On macOS, temp directory paths contain
underscores, causing a path mismatch.
