Quick fix for restore of backups made by dump fails silently

[jboonstra70]

When I use the restore command to restore previously backup made by dump, it seems everything works fine (no errors). But when I check the restored database it's only restored up to the first table with a big amount of rows. The dump is fine, because I can restore it succesfully with for example MySQL Workbench.

Found that the used scanner in databse restore package has a default buffer which has a maximum content which is too small for the long lines generated by dump. A possible work-around is to supply dump with maxAllowedPacket option with the max size of this default buffer.
Or supply the scanner with a buffer which can handle the long lines, like I did in this pull request.

• Added scanner buffer to max size same as defaultMaxAllowPacket from dump.
• Added error check scanner to alert something has gone wrong.

Looks good, thank you.
