apply_format range error

[dorbal]

Describe the bug
I tried to change a column format except the first cell, but the format was applied to the whole column. I took a look at the code and the bug probably caused by the GridRange.

To Reproduce
Steps to reproduce the behavior:

from pygsheets.address import GridRange
//...
grange1 = GridRange.create('G:G', wks)
grange2 = GridRange.create('G2:G', wks)
print(grange1.to_json())
print(grange2.to_json())

# see error
# Output:
# {'sheetId': '...', 'startColumnIndex': 6, 'endColumnIndex': 7}
# {'sheetId': '...', 'startColumnIndex': 6, 'endColumnIndex': 7} # <- it should be different
