Reading file and embedd file content in JS leads to

This issue was taken from: https://stackoverflow.com/questions/59489470/karate-dsl-how-to-read-token-string-from-arg-and-send-this-string-in-json-re

The following Scenario:

    Scenario: Test to read/write within karate..
        * def fileContent = 'xyz12345'
        * eval  karate.write(karate.get('fileContent'), 'aFile.text'); 
        * def fromFile = read('file:target/aFile.text')

        # This works:
        * match fileContent == fromFile

        * def fromFileEmbeddedInJs = fromFile + ""
        # This fails with error message:  path: $, actual: 'xyz12345', expected: 'java.io.FileInputStream@3114dcf3', reason: not equal
        * match fileContent == fromFileEmbeddedInJs

Results in this error message:

Same result with 0.9.5.RC5. Tested with latest adopt jdk 12 and 8 version. (log is is from jdk12)

Executed with vs-code karate runner + karate standalone and intellij idea - just mentioned, because there are some groovy type casting issues.

@peterquiel I made a commit that hopefully puts this discussion to rest, will close the PR

@peterquiel just to make sure I understand because this is a lot of indirection and is confusing to me

where test.foo is { "foo": "bar" }

* def tmp = read('test.foo')
* def bar = { baz: '#(tmp)' }
* print bar

this results in:

[print] {
  "baz": java.io.FileInputStream@4b7dc788
}

but one small change: * json tmp = read('test.foo') results in the expected behavior. what needs to change in karate ? and * string tmp = read('test.foo') would also work
