Generate SQL copy paste error

### Description

When trying to generate a insert, from an existing result:

This is the last thing that it copies:

And as you can see, in the Generated SQL popup, where it shows you the full generated insert for you to copy,
that is not the end of the query:

It always happens when there's values with spaces in it, like the ones we can see before the NULL values.

The actual solution is manually completing the " ' ' " that's causing the error and copy the rest of the query.

### DBeaver Version

26.0.5 and below

### Operating System

### Steps to reproduce

1. Perform a SELECT query.
