- updated packages to include performance improvement for NQL filter
strings including multiple neq filters for the same resource
- bumped `bookshelf-plugins`
- bumped NQL versions
We identified a performance fix that allows us to combine not equal
(neq) filters for the same resource in a logically-equivalent way that
also has far more performant resulting SQL.
We're effectively automatically combining strings like
'tag:-tag1+tag:-tag2` into 'tag:-[tag1,tag2]'.
fixes GRO-25
Updated @tryghost/nql to 0.12.0 and other packages that depend on it
1. SQLite: when a filter string contains /.
When we use a NQL contain/starts/endsWith filter that contains a slash,
underlyingly the whole filter will get converted to a MongoDB query, in
which we just use a regexp to represent the filter. In here we will
escape the slash: \/ as expected in a regexp. Later when we convert this
MongoDB query back to knex/SQL, we use a SQL LIKE query. Currently we
don't remove the escaping here for a normal slash. MySQL seems to ignore
this (kinda incorrect). SQLite doesn't like it, and this breaks queries
on SQLite that use slashes. The solution here is simple: remove the
backslash escaping when converting the regexp to LIKE, just like we do
with other special regexp characters.
2. We don't escape % and _, which have a special meaning in LIKE queries
Usage of % and _ is now as expected and doesn't have the special SQL
meaning anymore.

This changes how we fetch recommendations:
- Relations can be included in one query instead of extra queries
- Sorting is now possible by click or subscriber counts
no issue
When filtering and using the BookshelfRepository, you had to use the column names instead of the entitiy field names. This is fixed by adding a transformer. Long term we want to move the NQL parsing away from the repository and into the API layer, and pass along the Mongo filter probably.
