edc_parser&autocomp: Fix double click issue on WindowsOS

Summary:
Enventor window stops responding on double clicking "min" on Windows.
Because of approaching the index in which the cur_context doesn't exist, the crash happens.
*cur_context[] in parser_attribute_get() edc_parser.c

Test Plan:
1. launch enventor on Windows
2. add image using live edit
3. double click "min" on editor
