[BUGFIX] Exception editing inline mm with deleted child child

[BUGFIX] Exception editing inline mm with deleted child child

Have an inline m:m record and delete one child child that has an
intermediate record pointing to it. Opening the parent throws
a DatabaseRecordException.
The patch extends this exception to add tableName and uid, then
catches the exception in the inline data provider, creates a
nice error message as flash message and continues displaying record.
