Text: InvalidSignatureException after upgrade to 17

[xxKeith20xx]

After upgrading from 16.0.5 to 17.0 I get an integrity issue with the text app:

root # sudo -u www-data php occ integrity:check-app text
  - EXCEPTION:
    - class: OC\IntegrityCheck\Exceptions\InvalidSignatureException
    - message: Signature data not found.

Client details:

• OS: debian 10

Text app version:
1.02

PHP version:
7.3

Nextcloud log shows the following:

{"reqId":"MpEc6Q0okxS8q91iEVoK","level":3,"time":"2019-10-13T15:31:55+00:00","remoteAddr":"","user":"--","app":"PHP","method":"","url":"--","message":"file_get_contents(/nextcloud/apps/text/appinfo/signature.json): failed to open stream: No such file or directory at /nextcloud/lib/private/IntegrityCheck/Helpers/FileAccessHelper.php#41","userAgent":"--","version":"17.0.0.9","id":"5da3458c456f2"}

update:

Was able to fix with copying ./nextcloud/apps/text/ from nextcloud-17.0.0.tar.bz2 to my install, after removing the existing directory. This forced the web updated to re-check the Text app. All checks pass now.
