Remove the test for mime-type text/plain as this seems to be based on suffix only.

Files with .onc extension are not recognized as text/plain files. ONCNetworkParser should fail on non-text files, so this test is not necessary.

BUG=chromium-os:23248
TEST=Importing an onc file with .onc suffix should work.
