Bug in treatment of block comments

[cleve-fauna]

Entering a string like */**/* will cause the string to be interpreted by the severless plugin as ** as the /**/ will be falsely identified as a block comment and stripped from the input.

Relevant source code:

https://github.com/fauna-labs/serverless-fauna/blob/main/fauna/baseEvalFqlQuery.js#L45-L62

Reproduce:

~/workplace >> sls fauna deploy -c poc_config.yml
Fauna: Schema updating in process...
Fauna: Schema up to date
Fauna: Schema updating in process...
Fauna: function `poc` was created
 ✨  Done in 5.73s.
