Use basic parsing

[dgosbell]

Changes proposed in this pull request:

• Added the -UseBasicParsing parameter to all the calls to Invoke-WebRequest. This means that the user running commands that call this cmdlet does not need to have IE configured. This is useful if you are calling ReportingServicesTools commands from a SQL Agent job as the SQL Agent account may not have IE configured
• Added try/catch to Out-RsRestCatalogItemId function to prevent errors when calling methods like Out-RestFolderContent and the folder contains items like linked reports that do not return a known extension

How to test this code:

• Run Out-RestFolderContent on a folder containing a linked rdl report, it should report a warning, but run to completion
• Run a script using a login that does not have IE configured (such as running via a SQL Agent job)

Has been tested on (remove any that don't apply):

• Powershell 3 and above
• Windows Server 2012 R2 and above
• SQL Server 2017 and above

Any chance of this being merged? Stopping me from using ReportingServicesTools for TFS release.

The unit tests are not passing

https://ci.appveyor.com/project/jtarquino/reportingservicestools/builds/25245392/tests

For example
Failed to delete folder '/SUT_GetRsRestItemDataSource_3245bde6-acd5-40c7-8602-878239f34be7': Cannot bind parameter because parameter 'UseBasicParsing' is specified more than once. To provide multiple values to parameters that can accept multiple values, use the array syntax. For example, "-parameter value1,value2,value3"
