Remove findnexus from the ReduceSCD scripts

[Peter Peterson]

Since the mantid framework provides this functionality, just use that. The important bits for doing it are hiding in ​stresstesting.py near line 120:

def __verifyRequiredFile(self, filename):
  '''Return True if the specified file name is findable by Mantid.'''
  from mantid.api import FileFinder

  # simple way is just getFullPath which never uses archive search
  if os.path.exists(FileFinder.getFullPath(filename)):
    return True

  # try full findRuns which will use archive search if it is turned on
  try:
    candidates = FileFinder.findRuns(filename)
    for item in candidates:
      if os.path.exists(item):
          return True
  except RuntimeError, e:
    return False

  # file was not found
  return False

Put a modified version of this in the SCD scripts.
