[Install] Fix error reporting when schema sourcing fails.

[ridz1208]

When running the installdb.php step of the install and a patch from the 0000-** series fails, no error is being reported to the front end, only a warning in the error log.

@maltheism we assigned you the install issues for LORIS Monday. This is one of them. If you could look at them, that would be awesome!

We know that it will be 8 issues but I have a feeling they would all be related somehow and since you played with the install, you seemed like the best person to tackle them. Let us know if you have any issues.

@cmadjar @ridz1208 I'm not getting any output in my error log file when running the installdb.php on the 22.0-release branch.

@maltheism the error in the SQL file was fixed, so there's currently no error.. but if you modify something in the SQL schema so that it's not valid and try installdb.php you'll see that the error handling is broken

@driusan thanks for the explanation. I'll investigate that!
