fix(mojaloop/3032): configurable param option fixes

[vijayg10]

fix(mojaloop/3032): configurable param option fixes:

• When an element in the request is an array, that should be properly populated in the "Configurable Param" option
• When a property in the request body is selected in the Configurable Param dialogue, we are not able to select a different one immediately when we try to change our selection
• When we select "Previous Request" from "Configurable Param" option, it should get the openAPIDefinition of the selected request. Currently its trying to get the path based on the current openAPI definition.
