Unexpected creation of IMD file when using the same file prefix as a source file containing IMD domain metadata

Description

In relation to this thread: https://lists.osgeo.org/pipermail/gdal-dev/2016-July/044826.html

The Python bindings (2.0.2) for driver.Create() are copying IMD domain metadata and creating an IMD file, when the files are written to the same directory and with the same prefix as a file containing the metadata. This is unexpected behaviour for Create.

Test code replicated here:

import numpy
from osgeo import gdal

band =
"C:/Users/deschampsb/Desktop/test/LC80040242014245LGN00/LC80040242014245LGN00_B3.TIF"
outpath =
"C:/Users/deschampsb/Desktop/test/LC80040242014245LGN00/LC80040242014245LGN00_B3_test.TIF"

ds = gdal.Open(band)
proj = ds.GetProjection()
geot = ds.GetGeoTransform()
dn = ds.ReadAsArray().astype(numpy.float32)
ds = None

driver = gdal.GetDriverByName("GTiff")
ds_out = driver.Create(outpath, dn.shape[1], dn.shape[0], 1,
gdal.GDT_Float32)
ds_out.GetRasterBand(1).WriteArray(dn)
ds_out.SetProjection(proj)
ds_out.SetGeoTransform(geot)
ds_out.GetRasterBand(1).SetNoDataValue(0)
ds_out = None

Does not create the file when writing to another directory or using a different prefix:

outpath =
"C:/Users/deschampsb/Desktop/test/LC80040242014245LGN00/newname.TIF"
outpath =
"C:/Users/deschampsb/Desktop/test/new/LC80040242014245LGN00_B3_test.TIF"
