import modes not working for write operations

[sidphbot]

code snippet to reproduce:
via doltcli
write_rows(write_rows(dolt, "characters", TEST_ROWS, REPLACE, ["id"])

or via doltpy:
write_pandas(dolt, table_name, df, import_mode='replace')

both call _import_helper which refers to

doltcli/doltcli/utils.py

Lines 251 to 265 in a807c93

	def _get_import_mode_and_flags(
	dolt: DoltT, table: str, import_mode: Optional[str] = None
	) -> str:
	import_modes = IMPORT_MODES_TO_FLAGS.keys()
	if import_mode and import_mode not in import_modes:
	raise ValueError(f"update_mode must be one of: {import_modes}")
	else:
	if table in [table.name for table in dolt.ls()]:
	logger.info(f'No import mode specified, table exists, using "{UPDATE}"')
	import_mode = UPDATE
	else:
	logger.info(f'No import mode specified, table exists, using "{CREATE}"')
	import_mode = CREATE
	return import_mode

the checks force it to return only create/update mode depending on the existence of the table, replace/force-create modes are ignored

suggested change (MR #32 ) :

def _get_import_mode_and_flags(
    dolt: DoltT, table: str, import_mode: Optional[str] = None
) -> str:
    import_modes = IMPORT_MODES_TO_FLAGS.keys()
    if import_mode and import_mode not in import_modes:
        raise ValueError(f"update_mode must be one of: {import_modes}")
    elif import_mode:
        return import_mode
    else:
        if table in [table.name for table in dolt.ls()] and import_mode :
            logger.info(f'No import mode specified, table exists, using "{UPDATE}"')
            import_mode = UPDATE
        else:
            logger.info(f'No import mode specified, table exists, using "{CREATE}"')
            import_mode = CREATE

    return import_mode
