Bugfix/2312 database join meta conversion fix

[vdwals]

Addresses #2312 in case of using SQLite database join. While the driver returns column type NUMERIC, when fetching data it can either return Long or Double values. This is not supported by Hop. This fix should do the required conversion. Additionally, the expected Type in convertNumberToString is changed from Double to Number.

When I ran the compile and tests in a github workspace, I saw a failure in the engine compilation test

When I get time I will try on a different machine, but we need to have the build tests passed.

I will have a look into it. I did not want to create additional work of course. And I'm going to implement some kind of test for this issue.
