Project name is used in testId calculation, so patching it in the
reporter is too late. Instead we now save project suffix to the blob
report file and patch all project and test ids as well as project names
in the report merger
Attachments with `path` are stored as `resources/sha1.ext` zip entries
and extracted under `report-dir/tmp` when merging. This way normal
fs.readFile keeps working as before even thought the file path is
different. The clients should rely on `attachment.name` instead of
`attachment.path` when deriving user visible titles in the UI. If this
turns out not to be the case we can reconsider later.
