nimeval: calling evalScript more than once has no effect

[timotheecour]

import compiler / [ast, vmdef, vm, nimeval, llstream]
from os import getEnv

when defined(case1):
  proc evalString(code: string, moduleName = "script.nim"):auto=
    let stream = llStreamOpen(code)
    defer: llStreamClose(stream)
    let path = getEnv("nimc_D") & "/lib/"
    # let path = findNimStdLibCompileTime()
    var intr = createInterpreter(moduleName, [path])
    defer: destroyInterpreter(intr)
    intr.evalScript(stream)

  evalString("echo 1")
  evalString("echo 2")

when defined(case2):
  proc evalString(code: string, moduleName = "script.nim"):auto=
    let stream = llStreamOpen(code)
    defer: llStreamClose(stream)
    let path = getEnv("nimc_D") & "/lib/"
    # let path = findNimStdLibCompileTime()
    var intr = createInterpreter(moduleName, [path])
    defer: destroyInterpreter(intr)
    for i in 0..<10:
      intr.evalScript(stream)

  evalString("echo 5")

nim c --nimcache:/tmp/nim//nimcache/ -o:/tmp/nim//app -r -d:case1 --path:/Users/timothee/git_clone//nim//Nim/ bugs/nimeval/t03_n_is_not_nil.nim
1
???(0, 0) Error: internal error: n is not nil

=> that's just #9180 (not the issue I'm concerned with in this bug)

nim c --nimcache:/tmp/nim//nimcache/ -o:/tmp/nim//app -r -d:case2 --path:/Users/timothee/git_clone//nim//Nim/ bugs/nimeval/t03_n_is_not_nil.nim
5

=> that's another bug (this issue): nim shows no error but instead only runs the script once

actually what's happening here is that the stream is exhausted after the 1st intr.evalScript(stream) so subsequent calls have no effect as is expected (using an actual modules instead of a stream shows multiple executions); closing
