I519240547 extended the patch_sets table with a pushCertificate column
to store push the certificate that was used when pushing a signed
commit.
However, the column type VARCHAR(255) is too small for PGP certificate
descriptions. The column name was also misspelled as "pushCertficate"
(missing a 'i').
Extend the column from VARCHAR(255) to CLOB, as used in the account
table ssh key column. At the same time, correct the misspelling.
