Database: tryDelimite strict delimiteres matching (BC break!) [Closes #819]

Removed support for not-delimiting strings closed by quotes. This was possible only in drivers without quote as delimiter -> !(postgre|oci).

This is BC break and at the same time SECURITY fix.
Only possible way to include strings into query is by placeholder, which is implemented for all methods two months ago. See #1003

Something like this is no longer supported.
```php
$sqlBuilder->select('DATE_FORMAT(column, "%b %d %Y")');
```
It was not also intuitive, because this didn't work:
```php
$sqlBuilder->select("DATE_FORMAT(column, '%b %d %Y')");
```

Use 
```php
$sqlBuilder->select('DATE_FORMAT(column, ?)', '%b %d %Y');
```
