fix(typeorm): filter query wrongly generated

[joennlae]

This PR fixes this issue #401 and issue #321. As described there (#401) if one filters by a certain field. The return field alias is wrong for type ORM.

Looking at the log, I saw the following QUERY:

SELECT "Comment"."id" AS "Comment_id", "Comment"."text" AS "Comment_text", "post"."id" AS "post_id", "post"."body" AS "post_body", "post"."commentsId" FROM "comment" "Comment" LEFT JOIN "post" "post" ON "post"."commentsId"="Comment"."id" WHERE (Comment.postId = $1)

And doing tests directly in the database and works with this SQL (I added the quotes on WHERE it)

SELECT "Comment"."id" AS "Comment_id", "Comment"."text" AS "Comment_text", "post"."id" AS "post_id", "post"."body" AS "post_body", "post"."commentsId" FROM "comment" "Comment" LEFT JOIN "post" "post" ON "post"."commentsId"="Comment"."id" WHERE ("Comment"."postId" = $1)

source #401 (comment)

I was able to reproduce this. I then tried to fix it with these two lines:

https://github.com/joennlae/crud/blob/5687f88de66d7e56bbae228f1d0739de6241ae8a/packages/crud-typeorm/src/typeorm-crud.service.ts#L788-L789

This above two line didn't work when I started to do some sorting queries. Sorting still needs the alias without ".

Thank you all for this awesome project. I started using it today and I am already a big fan.
