Closes #1531

When it comes to starting with the test fix, there is some information that can help you:

Module: Vulnerability Detector
Support Team:  "binary beasts"
Target: Manager   
OS: Linux

I add some information obtained while researched the logs that failed.

In this case, there 2 different errors when it failed. For that, I will create 2 cases but the test is the same.
The idea is that you can analyze and fix both.

Case 1:

Type	Description
Test Path	test_feeds/msu/test_invalid_values_msu_feed
Consistent	yes
Test Execution	3/3 executions failed
Cases Fails	93
Summary	On modify_feed method when called read_json_file. The problem seems to be a Parser error when reading the file.
Error message	"ERROR at setup of test_invalid_values_msu_feed"

Case 2:

Type	Description
Test Path	test_feeds/msu/test_invalid_values_msu_feed
Consistent	yes
Test Execution	3/3 executions failed
Cases Fails	93
Summary	On test_invalid_values_msu_feed when called check_feed_imported_successfully the problem could be a Parser error when check in the log or a problem when file is imported.
Error message	"Could not find the message: 'Microsoft Security Update' feed finished successfully"

In order to finish this issue the following tasks should be fulfilled:

• Research of fails.
• Apply Fix
• Full Green/ Full Yellow in test_feeds/msu/test_invalid_values_msu_feed for 3 times.
• Documentation of any important change done for these tests or the used tools.
