Description

CacheManager#updateOutdatedCachedAccount
If isSingleTenant() returns true the following code is executed

const matchingAccountKeys = this.getAccountKeys().filter(
                (key: string) => {
                    return key.startsWith(accountEntity.homeAccountId);
                }
            );

matchingAccountKeys is [] because getAccountKeys() are in lower case (see: AccountEntity#generateAccountCacheKey)
but accountEntity.homeAccountId must not be in lower case.
