Conflict with PostMyFC7

Hi there

Your plugin and PostMyCF7 (https://ro.ww.wp.xz.cn/plugins/post-my-contact-form-7/) use the same function definition that gives a conflict when installed.

AH01071: Got error ‘PHP message: PHP Fatal error: Cannot redeclare get_cf7form_id() (previously declared in /wp-content/plugins/cf7-grid-layout/assets/cf7-admin-table/admin/cf7-post-admin-table.php:535) in /wp-content/plugins/post-my-contact-form-7/assets/cf7-admin-table/admin/cf7-post-admin-table.php on line 435\n’, referer: wp-admin/edit.php?post_type=wpcf7_contact_form&ids=5

Thank you
