Remove deprecated withConsecutive() implementation from ViewModeSwitchTest unit test

Problem/Motivation

Currently the ViewModeSwitchTest::testDoGetViewModeToSwitchTo() test method uses PHPUnit's deprecated withConsecutive() method. This should be replaced for future compatibility. See also #3306554: InvocationMocker::withConsecutive() is deprecated in PHPUnit 9.6 and removed from PHPUnit 10

Proposed resolution

• Use a similar approach as core does (e.g. in #3417560: Remove withConsecutive() in SqlContentEntityStorageSchemaTest)

Remaining tasks

• Create issue fork and MR to fix this issue
