M2.2.x: Fix the issue when saving a product in catalog admin panel

Issue:

I purchased and installed your Multistore view pricing extension version 2.2.1_ce_m2.2.6_to_m2.3.0 on Magento 2.2.9, but products are disappeared from the frontend, when I try to save a product in catalog admin panel it gives me error 500, when I run the indexer on catalog_product_price it gives this error 

Base table or view not found: 1146 Table 'satu_it.catalog_product_index_price_temp' doesn't exist, query was: SELECT `main_table`.`entity_id`, `main_table`.`customer_group_id`, `main_table`.`website_id`, `main_table`.`tax_class_id`, `main_table`.`price`, LEAST(main_table.final_price, rule_index.rule_price) AS `final_price`, LEAST(main_table.min_price, rule_index.rule_price) AS `min_price`, LEAST(main_table.max_price, rule_index.rule_price) AS `max_price`, `main_table`.`tier_price` FROM `catalog_product_index_price_temp` AS `main_table`
 INNER JOIN `catalogrule_product_price` AS `rule_index` ON rule_index.product_id = main_table.entity_id AND rule_index.website_id = main_table.website_id AND rule_index.customer_group_id = main_table.customer_group_id WHERE (rule_index.rule_date = '2020-06-29') AND (main_table.entity_id IN (34510, 34514, 34661))

Solution:

The issue happens since our module does not work well on Magento 2.2.x with version 2.2.1_ce_m2.2.6_to_m2.3.0.

It causes the error when saving a product in the catalog admin panel.

To fix this issue, we have modified the file app/code/Bss/MultiStoreViewPricingTierPrice/Model/Product/Attribute/Backend/Tierprice/UpdateHandler.php
