Robin Jarry 6b1afc3ae3 tests: fix errors after lint series
Fix the following test failures:

 FAIL: TestMessageInfoHandledError (0.00s)
 parse_test.go:53: could not parse envelope: date parsing failed:
 unrecognized date format:

 FAIL: TestReader (0.07s)
 gpg_test.go:27: using GNUPGHOME = /tmp/TestReader2384941142/001
 reader_test.go:108: Test case: Invalid Signature
 reader_test.go:112: gpg.Read() = gpgmail: failed to read PGP
 message: gpg: failed to run verification: exit status 1

Fixes: 5ca6022d00 ("lint: ensure errors are at least logged (errcheck)")
Fixes: 70bfcfef42 ("lint: work nicely with wrapped errors (errorlint)")
