Add shortcut tests for @param

[jannyHou]

Add shortcut tests for
@param.query.*
@param.header.*
@param.path.*

Take shortcuts @param.header.* as an example, the current test cases can be found in https://github.com/strongloop/loopback-next/blob/master/packages/openapi-v3/test/unit/decorators/param/param-path.decorator.unit.ts

The missing ones are:

• @param.path.long
• float
• double
• byte
• binary
• date
• datetime
• password

And add the same missing tests for @param.query.* and @param.path.*

Acceptance Criteria:

• Add missing shortcut test case for @param.header.*
• Add missing shortcut test case for @param.query.*
• Add missing shortcut test case for @param.path.*
