[various grammars] Missing and misplaced grammar input tests

[kaby76]

After noticing the http grammar not placing some test inputs in a directory called example/, I wrote a script to go through all the grammars and find missing examples/ directories.

Scanning the output quickly, I notice some misplaced tests for these grammars.

• http -- tests *.http not in examples/
• kirikiri-tjs -- directory called "example" not "examples"
• powerbuilder -- directory called "example" not "examples"
• powerquery -- directory called "example" not "examples"
• python/python2-js -- test.js not in examples/. In fact, the readme notes that test.js does not parse. Why in the world does this grammar exist when we have one that works?
• solidity -- test.sol not in examples/

Two recently added grammars, which are for popular programming languages, are sql/mysql/Oracle and graphql (not to be confused with GQL). Neither of these grammar have test inputs!

graphql has no readme.md.
