Also, some test refactoring and add servant-client to tests.

When user searched for a phrase with space inside, in database, the
'to_tsquery' function raised an sql error. One should use
'plainto_tsquery'. Also, a proper test was added.

Also, update README with remark about cabal.project.local file

This reverts commit 45fbb34a.

Historical post-mortem: I have tried to upgrade to LLVM-15 the Haskell stack,
but it didn't work out very well.

This commit introduces a slight variation to the `logStdOutDev`
middleware which is capable of redacting secrets from our gargantext
requests.

This way we can run the server in dev mode (for instrumentation
purposes) without leaking users' secrets.

Also, refactored NodeStory to use Prelude database.

This commit also uses a temporary fork of boolexpr.
It allows to parse certain terms like "Niki" without choking.
